Human error likely caused a glitch in China’s Great Firewall that saw millions of Internet users ironically rerouted to the homepage of a U.S.-based company which helps people evade Beijing’s web censorship, according to Reuters.

Hundreds of millions of people attempting to visit China’s most popular websites on Tuesday afternoon found themselves redirected to Dynamic Internet Technology (DIT), a company that sells anti-censorship web services tailored for Chinese users.  Sources familiar with the Chinese government’s web management operations told Reuters that a hacking attack was not to blame for the malfunction.  They said the incident may have been the result of an engineering mistake made while making changes to the “Great Firewall” system the Communist Party uses to block websites it deems undesirable – such as the DIT site.
